I don't really follow the 80 character rule, IMHO it is a bit outdated taking into account the size of computer screens nowadays. I tend to use about 100 characters per line but it is not a hard limit, i.e. I have to write, say, 5-10 characters over 100 I do that instead of using a new line.

But this is something personal. Not a strict rule followed here.

What I find weird here however is to break a long line into two lines and make the second one (notably) longer than the first one. In addition, writing a line break between the type and the name of a variable is odd in my opinion.
